This invention relatestofwindows, and

particularly to windows" in which theisashes swing about axesintermediate their ends;

I My invention is directed toward provisions for securing effective"screening windows of the specific type refg'e'rred' to,{--w'1th assura'nce of a perfect seal at the region of the swing'ng axes of the sashesthroughout they range of sash movement.

1 This desiderata I attain with means applicable to pivoted windows ofstandard construction, along'the swinging axes'ofltheir sashes,tocontinuously'contact with contigu- J ous edges of COmplementaIsCreens'atopposite 15 sides of said axes and respectively exteriorly andinteriorly of the windows, thereby to function as aseal'acro'ssthegapneces'sitated bysuch relative allocation of the screens.

With reference to the drawings, Fig. ;I'1s

avertical section through a window structure with a pivoted sash; andscreeningprovisions conveniently embodying my invention.

Fig, II is a view similar to Fig: If although morefragmentary'inflcharacter, showing the 11, of right angle cross section.Within the frame 10' is mounted .a sash 12 with a frame formed ofperimetric railjsf 13-.as well. as a a, conventional muntinorintermediate rail 14,

also of metallic angular cross section. The sash 12 is mounted formovement about a horizontal axis intermediate its ends on hingepivots 15in the present'inst'ance ofi'set inward somewhat but in line withth'erail 14,

I the hinges being such that the'upperrsash edge swings inward inopening. In closed position it will be'noted that the vertical flangesof the upper and lower rails 13j0 f the sash 12 contact with thehorizontal flanges of the outer frame rails 11,.respectively atthe128mSefial no. 2883401 wr nnow ooivsrrnuorrorr in and theout sidesof'thewindowstructure, sothat weather tight juncturesare formed at: thedesignated regions. suitable latch comprehensively designated-16 thesash 12 in closedposition'l I As hereinbefore pointed'out, the-present vinvention is concerned :with'screen protection .for a pivoted Windowofthe" type just briefly serves to lock 7 described. iTothisT'end Iprovideabove and below the pivot axis 15,1and respectivelyqiexteriorlyand interiorly the window-,iscreens "WlllCll are comprehensivelydesignatedby the numerals 20, 21in Figs.

this'angle strip 24 is fastened by screws 25 along'the upperrail l l ofthe frame 1(l',",and

The sealing strips 30,

ing. In the present instance I have shown them as-secured to theintermediate rail 14 of=the sash 12, the strip being angularlyconfigured as at 30?) to suit the contour of said rail and to admit' ofinterposition between said rail and the window pane 32, with thehorizontal flange 800 occasioned by the angulanbending at 30?) restingonthe web of the rail. The companion strip 31 is similarly flangedlaterally as at 31?), and flange, together with the flange 800' of thestrip 31, are concealed with'the putty or cement employed to securethe'glass 32 in place. The dissimilarity in the cross sectionalconfiguration-of the sealing strips'30, 31 is for the most part due tooffsetting of the pivot axis 15to one side ofthe plane of the sash 12.In cases where the pivot lies directly in'the medial plane of the sash,the aforesaid strips may be quite similar in shape, or even identical;

While I have specifically shown and described my invention in connectionwith a window having a sash swingable about a hori zontal pivot, it willbe obvious that the same can be embodied with advantages correspond- Iing to those herein set forth in windows having sashes swingable onvertical pivots interme diate ends.
